In this article we study the impact of teamwork on the organizations’ performance, 19 considering a cooperative game’s framework. To promote the teamwork culture, performance 20 indexes are considered individually and collectively, respectively, and by comparing the scores that 21 every employee earns individually and collectively, their differences become obvious. In this 22 approach, a cooperative games’ model is used in order to improve the organization’s performance. 23 The proposed model, in addition to evaluating the organization and employee's activities, can 24 implement all payments, including the overtime pay, reward, etc., fairly and along with increasing 25 performance and satisfaction. The cooperative approach creates effective communications between 26 employees and authorities and enhances their motivation for teamwork. Moreover, results can be 27 used for decisions related to employees (such as promotion, transition, firing, and detachment), 28 analysis of training requirements, employees’ development, and research and plan valuation. Our 29 findings show that the collaborative coefficient is a key factor in increasing productivity and 30 improving the efficiency of an organization in the long run. The collaborative coefficient is a new 31 concept in teamwork that has rarely been considered in scientific research
